192 Tournament wiring question

[hardasset]

I have undertaken running new wiring in my 2001 192 Tournament. The factory wiring is a mess.
does anyone know whether there is a bus bar for grounding in the bilge? I can’t seem to locate one and all of the wiring in the bilge is a complete rats nest.

I don't believe there is a ground bar. If there is, I've never seen it....

Common ground panel is on the fuse panel under the dash. Ground lead runs from there to the battery.
